Bone Carving Tool Convex Ridge Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During dental implant operations, the cortical bone is excessively incised and damaged, leading to issues with bone graft separation and economic burdens due to the generation of condensing pressure during bone extension, which results in breakage and inefficiencies in the implant placement process.
Innovation Solution
A bone carving tool with a convex ridge design for the inner border of the initial hole is used, allowing for the absorption of condensing pressure and preventing cortical bone breakage by forming a structure that can contract internally, enabling bone extension without external breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cortical bone is incised and the alveolar bone is split using a chisel, then the bone width can be increased for implant placement, but the cortical bone is significantly damaged and the damaged range increases
Solution Approach 1:
The patent applies preliminary action by forming a convex ridge structure at the inner border of the initial hole before bone extension. This pre-formed structure serves as a stress distribution mechanism that prevents cortical bone breakage during subsequent bone splitting operations, allowing safe bone width expansion without excessive damage
Solution Approach 2:
The convex ridge structure acts as a cushioning element that absorbs and distributes condensing pressure generated during bone extension. This beforehand cushioning prevents the pressure from concentrating at weak points and causing cortical bone breakage, thereby reducing harmful effects while achieving bone width increase
2Volume of moving object
If the cortical bone is significantly incised to extend the bone, then the bone width is increased, but bone graft materials and blocking membranes must be used which increases cost and complexity
Solution Approach 1:
By pre-forming the convex ridge structure before bone extension, the patent creates a protective framework that prevents cortical bone breakage. This preliminary structural preparation eliminates the need for subsequent bone graft materials and blocking membranes, simplifying the overall operation while achieving the desired bone width increase
3Ease of operation
If bone extension is performed without a convex ridge structure, then the operation is simpler, but condensing pressure causes cortical bone breakage from external side to internal side
Solution Approach 1:
The convex ridge structure is formed as a preliminary action before bone extension. This pre-formed structure serves as a stress distribution mechanism that prevents cortical bone breakage during the extension process, maintaining bone integrity while allowing the extension operation to proceed
Solution Approach 2:
The convex ridge acts as a cushioning structure that absorbs condensing pressure before it can cause cortical bone breakage. This beforehand protection mechanism ensures bone reliability during the extension operation without requiring complex procedures
